What to know before buying

Listing details to confirm

The listing is inconsistent about the mode count: it calls the product 13 modes, but describes five standard modes plus eight DIY levels. It also describes DIY and Pulse as button selections, and states the pressure range as 30–150 PSI without mapping it to individual levels. Confirm the control sequence and pressure details if these distinctions matter. The stated 30-day battery life has no usage conditions specified.

Who is it for?

A good fit for

People who want cordless water flossing with adjustable pressure for daily oral care.
Users with braces or bridges seeking a dedicated orthodontic nozzle, as claimed in the listing.

Frequently asked questions

How many modes and pressure levels does it have?

The listing names five standard modes—Low, Medium, High, DIY and Pulse—and eight DIY pressure levels. It also describes the product as having 13 modes, so the exact way modes and levels are counted is unclear.

What is included?

The listing's box description names the flosser, five replacement nozzles, a user manual and a figure-8 USB charging cable. It says the adapter is not included.

Can it be used with braces?

The listing includes an orthodontic tip and describes the flosser for braces and bridges. This is a product-use claim, not a guarantee of suitability for every dental situation.

How long does a tank fill last?

The listing claims up to two minutes per fill from the 300 ml tank.

Can it be used in the shower?

The listing claims IPX7 waterproofing and says shower use is possible, provided the charging port is closed.
